The main motivation behind this study is to evaluate the relationships among information and communication technologies (ICT), organisational practices, internationalization, innovation and human capital in a sample of Polish companies. To examine that we used the data from the Polish companies' survey conducted in 2015 for a representative sample of 805companies. Using ordinary least squares modeling, we examined determinants of labour productivity. Our study is one of the first empirical studies using this methodology for Polish companies.The principal finding that emerged from the study is that the presence of the ICT innovation was the main determinant of labour productivity. Moreover, other variables: operating on the international markets, education of the employees and executives and presence of the separate research and development department positively influence productivity. The results of the investigation bridge the gap in insufficient academic research about Central European countries and extend existing research on the company-level labour productivity determinants.
